How long can true nature be hidden?
The nature imprinted into your system at birth, written in the DNA passed on to you and running through your veins as an inseparable part of you. The nature ordained by the laws of the world to reveal itself at an appointed time.
How long can one be deceived?
Walking amidst people they consider kin bearing the same, eyes, skin but being inherently different from within.
One day the dormant nature lying in wait will slowly rouse from its slumber, unraveling bit by bit, taking over and causing change until one day a completely different person is seen in the mirrors' reflection.
Whether the change is good or bad is irrelevant, all that matters is that it's taking place and you're becoming who you were always meant to be.
